MECHANISM FOB OPERATING CONCENTRATING UNITS.

Specification of Letters Patent.

Patented Mar. 3. 191st.

Application filed July 30, 1913. Serial No. 782,085.

To all whom it may concern:

Be it known that I, WVILLIAM F. Dnrsrnn, residing at Fort Wayne, in thecounty of Allen and State of Indiana, a citizen of the United States,have invented or discovered certain new and useful Improve ments inMechanism for Operating Concentrating Units, of which improvements thefollowing is a specification.

Letters Patent Nos. 1,007 ,074 and 1,007,075, dated October 31st, 1911,show, describe and claim apparatus for treating concentrates, saidapparatus consisting generally stated in a series of superposedindependently plvoted decks, over which when inclined in one directionthematerial to be treated is allowed to slowly flow in a thin stream fora suitable period. The inclination of the decks is then reversed andwater allowed to flow with considerable rapidity from the elevated endsdown along the surfaces to wash off the minerals or values, which lodgedon such surfaces during the feed period. It is then generally thepractice to arrange a series of these apparatuses in batteries, and toshift the decks from one position to another in succession.

The invention described herein has for its object theautomaticsuccessive operation of the apparatuses forming a battery.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings forming a part of this specification,Figure 1 is a diagrammatic view showing a series of concentratingapparatus arranged in battery and the controlling mechanism; Fig. 2 is aside elevation of a single unit and the fluid pressure mechanism forshifting the decks; Fig. 3 is a front elevation of the mechanism forcontrolling the flow of fluid pressure to and from the several fluidpressure mechanisms operating the apparatus, and Fig. 1 is a plan viewof the controlling apparatus.

Each concentrating apparatus as set forth in the patents referred toconsists of a series of decks 1, independently supported in pivotalshafts carried by standards 2, and so connected together by straps 3 asto move in unison on their pivotal supports. Provision is made asdescribed and shown in the patents referred to to feed the material tobe treated, as for example, slime, onto their high ends when the decksare inclined as shown in Fig. 2. Provision is also made as by perforatedpipes 4 for discharging water onto the opposite ends of the decks, whentheir inclination has been reversed. The flow of slime and water isautomatically controlled by the decks when being shifted from oneinclination to the other.

It is preferred as set forth in the patents that the decks should be sopivotally supported that when free to move they will automaticallyassume feed posit-ion as shown in Fig. 2, but they may be positivelyshifted to both positions. In the construction shown a fluid pressurecylinder is supported on a frame arranged below the decks and at oneside of the pivotal points of the latter. The piston? of the cylinder isconnected to the underside of the lower deck. As the decks move in thearc of a circle, the cylinder 5 is provided with trunnions 7 which reston suitable bearings in the frame 6.

A short section 8 of flexible tubing connects the lower ends of thecylinders of the respective apparatus in the battery to lines of pipe 9,9, etc., extending to the controlling apparatus, which may be arrangedat any desired place. As in the construction shown herein the decks aremoved positively only from feeding to washing position and hence fluidpressure is admitted to and allowed to escape from only one end of thecylinder,

provision is made as by a pet cock 10 for the flow of air into and outof the opposite end of the cylinder.

As shown in Fig. 1, the lines of pipe lead to independent valvemechanisms in the controllcr. Each valve mechanism consists of an inletvalve 11 connected to a supply pipe 12 and to a pipe 9 leading to thefluid pressure cylinder, and an outlet valve 13 connected to pipe 9 andpreferably to an escape pipe 14. The stems 15 and 16 of the inlet andoutlet valves are adapted to be shifted to open said valves by a lever17, which is provided on opposite sides of its pivotal point with lugs18 and 19 preferably carrying rollers 20. The lever 17 is shifted firstin one direction and then in the other to open said valves in successionby a cam projection 21 on a movable head 22.

As before stated the number of valve mechanisms in the controller willcorrespond to the number of concentrating apparatus in the battery. Thevalve mechanism may be arranged in any desired manner and head 22 asshown in Fig. 4.

The time elapsing between the shifting of successive apparatus from feedto washing position will be dependent on the distance between successivevalve mechanisms and the rate of movement of the valve shifting head 22.But the interval between the movement of the decks of each apparatus towashing position and their return to feed position or in other words theduration of the washing operation, is dependent on the distance betweenthe lugs 18 and 19 on the levers and the rate of movement of the head22. As shown in Fig. 8, the positions of the rollers on the lugs 18 and19 may be changed to vary the interval between feeding and washingoperations.

I claim herein as my invention:

1. In a concentrating plant, the combina tion of a pluralitv ofconcentrating apparatus, each consisting of pivotally mounted decks, afluid pressure cylinder for each apparatus, a plurality of valvemechanisms each connected to a cylinder and adapted to control the flowof fluid pressure to and from said cylinder and a movable head foroperating said valve mechanisms in succession.

2. In a concentrating plant, the combination of a plurality ofconcentrating apparatus, each consisting of pivotally mounted decks, afluid pressure cylinder for each apparatus, a plurality of valvemechanisms, each connected to a cylinder, a head movable into operativerelation to said mechanisms successively the spacing of the mechanismsand the movement of the head being dependent on the desired duration ofthe feeding operation.

3. In a concentrating plant, the combination of a plurality ofconcentrating apparatus, each consisting of pivotally mounted decks, afluid pressure cylinder for each apparatus, a plurality of valvemechanisms each connected to a cylinder and each consisting of spacedvalves for controlling the flow of fluid pressure to and from acylinder, means for operating the valves of each mechanismindependently, a head for shifting the valve operating means, andmovable along the line of valve mechanisms, the

movement of the head and the spacing of the valve operating means foreach mechanism being dependent on the desired duration of the washingoperation.

l. In a concentrating plant, the combination of a plurality ofconcentrating apparatus; each consisting of pivotally mounted decks, afluid pressure cylinder for each apparatus, a plurality ofvalvemechanisms each connected to a cylinder and adapted to control theflow of fluid pressure to and from its cylinder, said mechanisms beingarranged at suitable intervals around a central point, a movable head,and means for mov ing said head around the central point to operativerelation to said valve mechanisms successively.

In testimony whereof, I have hereunto set my hand.
